FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 410,517, datedseptember 3. 1889- Application iiled April 24, 1889. Sen'al No. 308.386.(No model.)

To aZl whom t may concern:

Be it known that I, MAX HECKING, a subject of the Emperor of Germany,residing at Dortmund, in the Province of Vestphalia, in the Kingdom ofPrussia and Empire of Germany, have invented certain new and usefulImprovements in Apparatus for Heating and Purifying the Feed-Water ofSteam- Boilers; and I do hereby declare that the following is a feill,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to construct and use thesame,reference being had to the accompanying drawing, which is aperspective isometric view of my apparatus, with some of the partsbroken away to show the interior construction.

My invention relates to devices or apparatus for feeding water tosteam-boilers of that class which are provided with means for purifyingthe feed-water before it is fed into the boiler, so as to avoid unduesediment in the boiler, and has for its object to so construct anapparatus of that class as to utilize the exhaust-steam from the enginefor heat-ing the water.

Vtlith this object in view my invention consists in the detailedconstruction and combination of parts of the feed-water heating andpurifying apparatus, which will be hereinafter more fully described andclaimed.

Reference being had to the accompanying drawing, the letter B denotesthe well or reservoir from which the feed-water is drawn in the firstinstance through the suction-pipe a., which connects with the pump pthrough the valve d', having athree-way cock d2 and shortconnecting-pipe d. The valve-cock (Z2 being adjusted, as illustratedonthe drawing, the feed-water is pumped in the direction of the arrows,through pipe l) and the air-compressing chamber NV, into thespraying-pipe o', which is provided with a rose b2 at its upper end,projecting into the lower part of the open-mouthed drum or cylinder D.The latter is mounted upon and forms an upward extension of aclosed tankor receiver R, which is placed at a suitable elevation upon a scaffoldor supporting-frame C. This tank R is provided on one side near..its topwith a faucet u, and in the top with the escape pipe or funnel c. Y

Projecting through one side of tank R is a pipe E, having an enlargementor chamber O, in the top of which is fastened a vertical tube F, ofglass, or of metal with a glass strip or window running its entirelength and open at the top. Chamber O connects, by a pipe G having avalve g, with the bottom of a second tank or reservoir R', having afaucet j', and provided near its bottom with the pipe e, leading to andcommunicating with the pump p', from which another pipe 7L leads to theboiler.

The mouth or upper end of the cylindrical drum or extension D maybeclosed by means of a Valve t', and is provided with a pipe j, open atits outer end and having a branch pipe la, which communicates with theexhaustports of the engine. At the junction of these pipes j and k is athree-way valve l.

Having in the foregoing described in detail the construction of theapparatus,I shall now proceed to describe its operation, which is asfollows: The valve t' in the top of drum D having been closed and thethree-way valve Zad j usted, as shown in the drawing-#26., closing theoutlet-pipe j and opening communication between the steam-pipe 7.5 andthe drum-steam will enter the drum D and at the same time pump p is setworking, which pumps water (valve-cock d2 being first properly set oradjusted) from the reservoir B into the lower end of the drum orcylinder, delivering the same through the sprayer or rose h2 in the formof a fine continuous spray. Meeting the jet of steam from. pipe k,(indicated by the arrow,) the spray is thoroughly heated and projectedto the bottom 0f tank R, the excess of steam which has not beencondensed by the spray passing off through pipe c.

The level of the hot water in tank R may be ascertained by means of thegage-glass F, and should the tank become too full the excess of watermay be drawn off through the faucet u.

The hot water in tank R escapes through pipe E, chamber O, and pipe Ginto the sediment-collecting tank R (valve gbein g open,)

IOO

from which the mud or fluid sediment may be drawn off through faucet f,while the clear feed-water is fed to the boiler through pump p and pipeh.

The steam for operating the feed-pump p is supplied from the boilerthrough pipe h.

If it is desired to reheat the water in tank R before .feeding it to thesecondary tank R and the boiler, then this may be accomplished in asimple and expeditious manner by closing valve g in pipe G and soadjusting valve d as to shut off connection with pipe a, but open itwith pipe fm, which results in pump p circulating the water for anydesired length of time from tank R through pipe E, chamber O, pipe m,with its connecting part or branch of pipe G, valve d', pipe cl, pump p,and pipe b b into the cylinder or dome D and back to tank R.Thefeed-Water having been heated in this manner to the proper degree oftemperature, valves CZ and g are readj usted, and the feed-water is nowdrawn froln tank R into the sediment or secondary tank R', ready to befed to the boiler.

By heating the feed-water in the dome D in the form of afinely-comminuted spray, the impurities in the water are projected ingreat part in the form of sediment into the bottom of tank Rk below theoutlet E, and may be drawn off at suitable intervals through the bottompipe o. Such liner particles as are not projected to the bottom of thistank, but pass with the feed-water through pipe G, will settle in thesecondary tank R', as a1- ready described, before the feed-Water reachestheboiler.

By opening thc valve t' in the top of the Having thus described myinvention, IV

claim and desire to secure by Letters Patent of the United States- Theherein-described apparatus for heating and purifying the feed-Water forsteamboilers, consisting of the following combined and (zo-operativeparts, Viz: tank R, having pipes c and v and faucet u, heating-dome D,having valve 'L' and branched pipe j 7s, provided With the valve l,water-pipe b b', having air-chamber W and rose or spraying nozzle b2,discharge-pipe E G,having gage-chamber O, provided with the gage-glass Fand valve g, secondary or sediment tank R', connecting-pipe e, feed-pumpp', suction-pipe` a', valve d', having three-way cock d2,connecting-pipe d, pump p, and branch pipe m, all constructed andcombined to operate substantially in the manner and for the purposeherein set forth.
